What we ship, and how we treat your work.
Eight short sections covering the product status, the technical limits, and the privacy decisions. No legalese.
Private by default. We don't make uploads public, ever. You own what you export.
Every release, in plain English. Newest at the top.
What's in progress, what's planned, what's on the backlog. Honest priorities.
Chrome 110+, Firefox 115+, Safari 16+, Edge 110+. Mobile is view-only.
STL ≤ 100 MB, OBJ ≤ 50 MB, 3MF ≤ 80 MB. Up to 200 primitives per scene.
What we don't ship yet — curved-surface text, multi-user editing, mobile editing.
Your exports are yours. Published designs use the license you pick.

File size & import limits
- STL import100 MB≈ 2 million triangles. Larger files take longer to parse but still work.
- OBJ import50 MBVertex colours and UV coords are ignored on import; geometry only.
- 3MF import80 MBMulti-part hierarchy + per-part settings carry across.
- SVG import2 MBExtruded into a polygon primitive.
- Image (image-to-3D)8 MBJPG / PNG / WebP. Used by Meshy.ai (third-party AI integrated into the workflow).
- Voice clip (Whisper)30 secondsLonger clips are truncated. Most voice edits fit in 2–5 seconds.
- Texture / lithophane image16 MBResized to 2048 px on the longest edge before sampling.
- Gallery thumbnail upload1 MBAuto-generated from the workspace if you don't upload one.
Known limitations
Text glyphs sit on a flat plane today — wrapping a label onto a cylinder rim or sphere needs face-picking + per-glyph raycast. Planned, not shipped.
Above ~200 positives + negatives the CSG engine starts to slow. Group complex sub-assemblies into a single grouped primitive to stay under the cap.
Phones + tablets can VIEW any design, but creating one needs a desktop browser. Touch-first gizmos are on the roadmap.
AI generation is gated to 13 free generations per calendar month (double for Contributor Lifetime). Meshy.ai is a third-party service — its uptime sits outside our control; we retry transient errors for up to 5 minutes.
Designs are single-user today. Yjs-based CRDT collaboration is on the P2 backlog.
Heavy server-side slices share an OrcaSlicer worker pool. During peak hours you may wait 5–30 seconds in queue. Local-browser slicing is always immediate.
Design ownership
- Creators keep ownership — always
Designing something in ForgeSlicer makes you the creator. You hold the copyright on your original work whether you share it or not. ForgeSlicer makes no claim on your designs or exports — no watermarks, no invisible identifiers.
- Exporters get a license, not ownership
Downloading someone else's published design gives you a usage license — what you can do with the exported STL / 3MF / OBJ / G-code is governed by the creator's choice (CC-BY-4.0 default; CC0, GPL, all-rights-reserved also available). Respect the license: attribute when required, don't redistribute non-redistributable work.
- Derivative works follow the same rule
If you modify a downloaded design into something functionally different, the derivative is YOUR work — subject to the original license's redistribution terms. Trivial edits (rescale, recolour, repose) don't transfer ownership; substantive design changes do.
- Published gallery designs use a license you choose
When you publish to the public Gallery, you pick the license that applies to the published version (CC-BY-4.0 default; CC0, GPL, all-rights-reserved also available). The license governs how OTHER users may remix or redistribute the published version. Your private original is unaffected.
- Remixes carry attribution
When someone clicks 'Customize in ForgeSlicer' on a public design, the resulting remix records its parent — the original author stays credited. You can disable remixing on your published designs in the Share dialog.
- Pre-existing IP
ForgeSlicer is a tool; what you design with it is your responsibility. Don't publish designs that infringe someone else's copyright, trademark, or patents.
